The invention relates to an electric motor with integrated stator cooling channels and a method of manufacturing the same. An electric motor includes a stator core and a plurality of stator windings disposed on or in the stator core, the plurality of stator windings including a plurality of winding end turns extending from the stator core. The electric motor also includes an electrically insulating potting material applied over the plurality of winding end turns. A cooling channel is formed that defines a cooling circuit through which a cooling fluid circulates to provide cooling to the plurality of winding end turns, the cooling channel being formed as soon as a chemically soluble material embedded within the potting material is dissolved. 本公开涉及具有集成的定子冷却通道的电动机及其制造方法。电动机包括定子芯和设置在定子芯上或定子芯中的多个定子绕组，多个定子绕组包括从定子芯延伸出的多个绕组端匝。电动机还包括施加在多个绕组端匝上的电绝缘的灌封材料。形成冷却通道，该冷却通道限定冷却回路，冷却流体通过该冷却回路循环以对多个绕组端匝提供冷却，冷却通道是一溶解了嵌入灌封材料内的化学可溶材料就形成的。
